You should only import the methods that you use.

If possible, write new programs in Python 3.x (where paretheses are required 
for print()).

Try PyDev or LiClipse with PyDev instead.

Define “filelist” which needs to refer to an iterable value.  Also, you have 
forgotten to end the “for…in” statement with a semicolon, and you need to 
unindent it one level if it is to make sense.

You have indented the “except” clause one level too many.  It must start at 
the same column as the corresponding “try” clause.  In Python, indentation 
works like block braces in C-like programming languages.  Do not mix spaces 
and tabs for indentation.

Follows from the above.  Standalone “try” clauses are not allowed.

See above.  Summary (untested):

from PIL import Image
from os.path import splitext

filelist = ["foo", "bar"]

for inputfile in filelist:
    outputfile = splitext(inputfile)[0] + ".jpg"
    if inputfile != outputfile:
        except IOError:
            print("unable to convert", inputfile)
